Financial liberalization and bank risk-taking: International evidence

This paper analyzes the channels through which financial liberalization affects bank risk-taking in an international sample of 4333 banks in 83 countries. Our results indicate that financial liberalization increases bank risk-taking in both developed and developing countries but through different channels. Financial liberalization promotes stronger bank competition that increases risk-taking incentives in developed countries, whereas in developing countries it increases bank risk by expanding opportunities to take risk. Capital requirements help reduce the negative impact of financial liberalization on financial stability in both developed and developing countries. However, official supervision and financial transparency are only effective in developing countries.     

Foreign bank entry and bank competition: Cross-country heterogeneity

This study investigates the impact of foreign bank entry on bank competition in the host countries. Using data for 148 countries over 1987–2015, I find that although on average an increase in the number of foreign banks is associated with more competition in the host country, competition increases in developed but decreases in developing countries. Stringent capital requirements, higher market entry barriers, and effective credit information sharing can mitigate the impact of foreign bank entry, while better supervision and external governance strengthen the link between foreign bank presence and competition. The findings justify the regulations on bank capital adequacy and call for an effective credit information sharing mechanism.     

Mergers,acquisitions, and bank efficiency: Cross-country evidence from emerging markets

In emerging countries, bank mergers and acquisitions (M&A) are frequently motivated by the objective of promoting stability in the banking industry. However, the evidence that M&A can lead to better performing banks is tenuous at best. In this article, we investigate if this tenuous relationship could be due to the treatment of target and acquiring banks as the same type in empirical analysis, which overlooks the possibility that M&A may affect these banks differently. Using panel data on six emerging countries, our results confirm that the effect of M&A is generally weak except when our regressions are implemented separately for target and acquiring banks. For the latter, we find that target banks tend to be more efficient after an M&A but no efficiency improvements are found for acquiring banks. These results suggest that in emerging countries, bank M&A can lead to efficiency improvements for the combined entity, although target banks are mainly the ones to benefit from it. They also highlight the importance of distinguishing between target and acquiring banks so as to obtain sharper estimates of how M&A might affect bank performance.     

National culture and bank risk-taking

We investigate the relation between national cultural values and bank risk. Despite the rigid transnational regulatory oversight of systemic European banks, we find evidence of an economically significant association between cultural values and domestic bank risk. Specifically, we report a positive (negative) association between the cultural values of individualism and hierarchy (trust) and domestic bank risk-taking. Consistent with our predictions, this relation weakened during the recent financial crisis and does not hold for global banks, regardless of the period under investigation. Our findings are robust to endogeneity tests that mitigate concerns regarding reverse causality and confounding effects affecting our conclusions.     

The non-monotonic impact of bank size on their default swap spreads: Cross-country evidence

This paper studies the drivers of bank's credit default swap (CDS) spread, taken as a measure of credit risk, by considering the impact of housing market along with a number of bank level determinants, such as regulatory capital, leverage, size, liquidity, asset quality and operations income ratio. We build upon a unique dataset consisting of 115 banks (during pre- and post-crisis periods) headquartered in 30 countries from both developed and emerging countries. Results suggest that CDS spread is driven by asset quality, liquidity and operations income ratio, while bank size is found to have a non-monotonic impact on CDS spread. If the bank is small, an increase in size reduces the average credit risk. If the bank is large enough, an increase in size raises the latter. From our results we derive the level of bank size that minimizes the CDS spreads. Financial institutions growing beyond this threshold are subject to higher credit risk, implying that smaller and medium sized banks are safer than large banks. When considering the estimates in the periods before and after the 2007 crisis, we further find a different extreme point of bank size in the former (approximately 1642 billion Euros) relative to a significantly lower level of optimal bank size (around 70 billion) in the post-crisis period, implying too-big-to-fail and too-big-to-save in the pre-crisis regime.     

Interest rates and bank risk-taking

A recent line of research views the low interest-rate environment of the early to mid 2000s as an element that triggered increased risk-taking appetite of banks in search for yield. This paper uses approximately 18000 annual observations on euro area banks over the period 2001-2008 and presents strong empirical evidence that low-interest rates indeed increase bank risk-taking substantially. This result is robust across a number of different specifications that account, inter alia, for the potential endogeneity of interest rates and/or the dynamics of bank risk. Notably, among the banks of the large euro area countries this effect is less pronounced for French institutions, which held on average a relatively low level of risk assets. Finally, the distributional effects of interest rates on bank risk-taking due to individual bank characteristics reveal that the impact of interest rates on risk assets is diminished for banks with higher equity capital and is amplified for banks with higher off-balance sheet items.     

Capital regulation and bank risk-taking: A note

This paper examines theoretically the effects of more stringent capital regulation on bank asset portfolio risk. The analysis shows that, for a value-maximizing bank, incentives to increase asset risk decline as its capital increases. Thus, as long as regulatory efforts to contain asset risk and size are not reduced, more stringent capital regulation unambiguously reduces the expected liability of the deposit insurance system.     

Countercyclical prudential buffers and bank risk-taking

We investigate the effects of countercyclical prudential buffers on bank risk-taking. We exploit the introduction of dynamic loan loss provisioning in Spain, mandating that banks use historical average loss rates in their estimation of loan loss provisions. We find that dynamic loan loss provisioning is associated with reductions in timely loan loss provisioning. Banks that previously recognized loan losses in a timely fashion exhibit the greatest reductions in timeliness and consequently extend loans to riskier borrowers with lower accounting quality. Our results have policy implications for the debate on the use of financial reporting requirements in mitigating capital pro-cyclicality.     

Political institutions and bank risk-taking behavior

This paper examines the impact of political institutions on bank risk-taking behavior. Using an international sample of banks from 98 countries over the period 1998–2007, I document that sound political institutions stimulate higher bank risk-taking. This is consistent with the hypotheses that better political institutions increase banks’ risk by boosting the credit market competition from alternative sources of finance and generating the moral hazard problems due to the expectation of government bailouts in worst economic conditions. While it is contrary to the hypotheses that better political institutions decrease banks’ risk by lowering the government expropriation risk and the information asymmetries between banks and borrowers. The results are robust to a number of sensitivity tests, including alternative proxies of bank risk-taking and political institutions, cross-sectional bank- and country-level regressions, endogeneity concerns of political institutions, country income levels, explicit deposit insurance schemes and sample extension from 1998 to 2014. I also examine the interdependence between political and legal institutions and find that political and legal institutions complement each other to influence bank risk-taking behavior.     

Financial statement comparability and bank risk-taking

This study examines the relationship between financial statement comparability and bank risk-taking. Our analysis of a sample of publicly listed U.S. banks over the 1994–2019 period shows that banks with more comparable financial statements are related to significantly less risk-taking. We also find that the negative relationship between comparability and risk-taking is more pronounced for firms with more severe moral hazard and agency problems. Our documented findings are robust across alternative measures of comparability and risk-taking and considering change analysis, after controlling for strength of corporate governance and using propensity score matching and two-stage least squares estimation to address endogeneity concerns. Our analysis also shows that the relationship between financial statement comparability and bank risk-taking is stronger for smaller banks than for larger banks. Overall, this study provides unique insights into the role of financial statement comparability in curbing risk-taking in the banking sector.     

Chair-CEO generation gap and bank risk-taking

Poor bank governance has disastrous consequences for economies as the 2007–2009 financial crisis has shown. In the aftermath, board diversity is identified as an effective mechanism to enhance bank governance. Diversity, creating cognitive conflict between board members, is expected to enhance board's independence of thought to better perform monitoring and advising functions. Age is a key demographic measure and age dissimilarity between the chair and the CEO in non-financial firms leads to better economic outcomes (Goergen, Limbach, & Scholz, 2015). In this paper, we examine whether chair-CEO age dissimilarity can mitigate banks' excessive risk-taking behaviour. Using a unique sample of 100 listed banks in Europe between 2005 and 2014, we find that age difference between the chair and the CEO reduces bank risk-taking. A chair-CEO generational gap –defined as a minimum of 20 years' age difference– has a larger impact in reducing risk-taking.     

Required CEO stock ownership: Consequences for risk-taking and compensation

In response to corporate governance concerns, SEC disclosure rules, and pressure from Institutional Shareholder Services, most large U.S. public firms have adopted executive stock ownership requirements (‘SORs’) in recent years. Compared to CEOs already in compliance, CEOs who have not yet fulfilled the requirement at adoption subsequently increase stockholdings, exposing themselves to more company-specific risk, potentially providing risk-reduction incentives and diminishing their subjective valuation of firm equity. We find that these CEOs on average subsequently reduce firm risk through diversifying M&A, less financial leverage, and smaller R&D investment. They experience a deterioration in firm performance and valuation, each associated with firms that do reduce risk, but receive significantly increased stock grants. Our evidence suggests that boards should exercise judgment when adopting this popular governance initiative.     

Institutional investor horizon and bank risk-taking

We test the effect of short-term versus long-term institutional shareholding –so-called investor horizon– on bank risk-taking. We find that in contrast to banks dominated by short-term shareholders, banks with greater long-term shareholding are associated with lower risk, better stock performance, and conservative business and compensation policies. Our results imply that bank regulators should be more vigilant over the actions of banks that heavily rely on short-term shareholding.     

Financial development and innovation: Cross-country evidence

We examine how financial market development affects technological innovation. Using a large data set that includes 32 developed and emerging countries and a fixed effects identification strategy, we identify economic mechanisms through which the development of equity markets and credit markets affects technological innovation. We show that industries that are more dependent on external finance and that are more high-tech intensive exhibit a disproportionally higher innovation level in countries with better developed equity markets. However, the development of credit markets appears to discourage innovation in industries with these characteristics. Our paper provides new insights into the real effects of financial market development on the economy.     

Muslim CEOs and bank risk-taking: Evidence from Indonesia

This study investigates the relationship between Muslim CEOs and bank risk-taking based on Indonesian banks from 2010 to 2017. We find that there is no significant difference in risk-taking among Indonesian banks based on whether the banks have Muslim CEOs or not. However, we find that only state-owned banks with Muslim CEOs display significantly low risk-taking. We further find that foreign-owned banks with Muslim CEOs display a significant low risk-taking only in the presence of Muslim-dominated boards. We show that Muslims must be in the majority on 2-tier boards (board of directors and board of commissioners) to significantly influence Muslim CEOs' risk-taking. In addition, we find no related evidence from family-owned firms. Further analysis reveals that banks with a low concentration of ultimate ownership indicate Muslim CEOs' low risk-taking behaviour, and vice versa.     

CEO ownership, external governance, and risk-taking

This paper shows the relation between CEO ownership and firm valuation hinges critically on the strength of external governance (EG). The relation is hump-shaped when EG is weak, but is insignificant when EG is strong. The results imply that CEO ownership and EG are substitutes for mitigating agency problems when ownership is low. However, very high levels of share ownership can reduce firm value by entrenching the CEO and discouraging him from taking risk, unless mitigated by strong EG. We identify channels through which CEO ownership affects firm value by examining R&D, which is discretionary and risky. We find CEO ownership similarly exhibits a hump-shaped relation with R&D when EG is weak, but no relation when EG is strong. Our results are robust to endogeneity issues concerning CEO ownership and EG.     

Financial networks,bank efficiency and risk-taking

Networks with a core–periphery topology are found in many financial systems across different jurisdictions. Though the theoretical and structural aspects of core–periphery networks are clear, the consequences that core–periphery structures bring for banking efficiency stand as an open question. We address this gap in the literature by providing insights as to how the structure of financial networks can affect bank efficiency. We find that core–periphery structures are cost efficient for banks, which is a characteristic that encourages the participation of banks in financial networks. On the downside, we also show that core–periphery structures are risk-taking inefficient, because they imply higher systemic risk levels in the financial system. In this way, regulators should be aware of the excessive risk inefficiency that arises in the financial system due to individual decisions made by banks in the network.     

CEO pay incentives and risk-taking: Evidence from bank acquisitions

We analyze how the structure of executive compensation affects the risk choices made by bank CEOs. For a sample of acquiring U.S. banks, we employ the Merton distance to default model to show that CEOs with higher pay-risk sensitivity engage in risk-inducing mergers. Our findings are driven by two types of acquisitions: acquisitions completed during the last decade (after bank deregulation had expanded banks' risk-taking opportunities) and acquisitions completed by the largest banks in our sample (where shareholders benefit from ‘too big to fail’ support by regulators and gain most from shifting risk to other stakeholders). Our results control for CEO pay-performance sensitivity and offer evidence consistent with a causal link between financial stability and the risk-taking incentives embedded in the executive compensation contracts at banks.     

National culture and bank risk-taking: Contradictory case of individualism

Previous studies have reported a positive association between the cultural dimension of individualism and bank risk-taking. We hypothesize that this association is likely to be confounded by the omitted effects of corporate governance. Given the indicative evidence that such confounders are less likely to affect listed banks, we test this association for a global sample of 467 commercial listed banks from 56 countries. Our results show that the association between individualism and bank risk-taking is negative. This result is consistent with the cushioning hypothesis, the idea that people take on more risk in collectivist societies because they expect to receive help from the members of their social networks in the case of failure.     

Macroeconomic determinants of growth: Cross-country evidence

Using post-war data from forty-seven countries, we examine the cross-sectional relation between the mean growth rate of real product (growth) and variables suggested by the theoretical literature. Barro's hypothesis that the variability of monetary shocks adversely affects growth receives strong support, as do several other hypotheses. We also show that our variables influence growth by affecting both the fraction of product devoted to investment and the return to capital. Finally, while an index of civil liberty explains growth only marginally, it dominates the other variables in explaining investment.
